From d09c38726c78effaf910a1e3f31e247b5b031d56 Mon Sep 17 00:00:00 2001 From: Miles Chen Date: Fri, 24 Sep 2021 15:43:38 -0700 Subject: [PATCH] scripts/sorttable: riscv: fix undeclared identifier 'EM_RISCV' error Fix the following build failure reported in [1] by adding a conditional definition of EM_RISCV in order to allow cross-compilation on machines which do not have EM_RISCV definition in their host. scripts/sorttable.c:352:7: error: use of undeclared identifier 'EM_RISCV' EM_RISCV was added to in glibc 2.24 so builds on systems with glibc headers < 2.24 should show this error.
